cds-question@unistra.frgalaxiesx-ray-sourcesaccretionx-ray-binary-starsWe have created a new, clean catalogue of extragalactic non-nuclear X-ray sources by correlating the 3XMM-DR4 data release of the XMM-Newton Serendipitous Source Catalogue with the Third Reference Catalogue of Bright Galaxies and the Catalogue of Neighbouring Galaxies, using an improved version of the method presented in Walton et al. (2011MNRAS.416.1844W, Cat. J/MNRAS/416/1844). Our catalogue contains 1314 sources, of which 384 are candidate ultraluminous X-ray sources (ULXs). The resulting catalogue improves upon previous catalogues in its handling of spurious detections by taking into account XMM-Newton quality flags. We estimate the contamination of ULXs by background sources to be 24 per cent. We define a 'complete' subsample as those ULXs in galaxies for which the sensitivity limit is below 10^39^erg/s and use it to examine the hardness ratio properties between ULX and non-ULX sources, and ULXs in different classes of host galaxy. We find that ULXs have a similar hardness ratio distribution to lower-luminosity sources, consistent with previous studies. We also find that ULXs in spiral and elliptical host galaxies have similar distributions to each other independent of host galaxy morphology, however our results do support previous indications that the population of ULXs is more luminous in star-forming host galaxies than in non-star-forming galaxies. Our catalogue contains further interesting subpopulations for future study, including Eddington Threshold sources and highly variable ULXs. We also examine the highest-luminosity (L_X_ >5x10^40^erg/s) ULXs in our catalogue in search of intermediate-mass black hole candidates, and find nine new possible candidates2019MNRAS.483.5554Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/5554CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/155 : Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)IX/44 : XMM-Newton Serendipitous Source Catalogue 3XMM-DR4 (XMM-SSC, 2013)J/AJ/127/2031 : Catalog of neighboring galaxies (Karachentsev+, 2004)J/MNRAS/416/1844 : 2XMM ultraluminous X-ray source candidates (Walton+ 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/5554https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/5554http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/5554https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/5554https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/5554http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/5554GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/5554/catalog (Extragalactic X-ray source catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/5554/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/5554/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/5554/catalog?GETtext/xml+votable180.050000true0.48049-15.430890.0055555555555555566/975 1701 2227 2251 2273 2343 2409 2622-2623 2708-2709 2774 2777 2780 3042 3446 3506-3507 3519 4352 4439 4447 4575 4695 4804 5067 5183 5241 5545 5618 5629 5715 5727 5975 5980 6977 7241 7424 7426 7536 7604 7606 7624 7659 7741 7743 7799 7869 7878 7921 7956 7969 7986 7989 8028 8085 8106 8173 8195-8196 8225 8440 10217 10378-10379 10414 10422 10440 10637 10761 10769 10841 10856 10888 10905 10911-10912 10977 10979 10982 11026-11027 11127 11375 11389 11791 11874 12122 13522 13529 15056 15592-15593 16120 16701 16898 17165 17286 17472 17520 17582 17606 17677 17688 17696 17754 17772 18071 18209 18398 18809 18941 19611 20000 20060 20090 22915 23075 24733 24740 24920-24922 24958 25079 25083 25100 25132 25245 25344 25383 25603 25635 25705 25742 25972 26090 26125 26265 26271 26303 26313 26346 26365 26432 26472 26858 27351 27466 27554 27580 27652 27669 27704 27714 27718 27721 27738 27763 27767 27773 27803 27860-27861 27907 27914 27918 27934 27936-27938 27944-27945 27948 28033 28035 28054 28075 28123 28141-28142 28149 28167 28221 28249 28251 28492 28495-28496 28515 28522 28535 28541 28593 28631 28637 30027 31406 33176 33193 33228 33802 33920-33921 33954 34170 34272 34334 34492-34494 34531 34533 34535 34540 34913 34915 35147 35243 35365 35536 35538 35576 35623 35691 35770 35928 35969 36231 36247 36785 36990 37012 37306 37388 37559-37560 38129 38139 38704 38868 39862 40216 40514 40520 40642 41434 42113 43214 43233 43306 43339 43420 43450 43503 43626 43825 43828 43843 43874 43877 43881 43898 43941 43977 44357 44626 45754 45821 45912 45914 46156 46170 46363 46399 46442 46477 46495 46525 46568 47047 47178 47181 47187 47383https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/5554?format=asciiX-raydefaultJ/MNRAS/483/5554/catalogExtragalactic X-ray source catalogueSrcID3XMM Source ID (SRCID)meta.id;meta.maininte_SHR1? 3XMM error on SHR1 (SC_HR1_ERR)stat.errordoublenullablerecnoRecord number assigned by the VizieR team.
